Analytics Queries filters none

When using the /analytics/queries I cannot use the none filter to exclude certain searches done on the Elastic Search portal itself.

`"filters": {"none": [{"tag": "swiftype_dashboard"}, {"tag": "swiftype_dashboard_query_tester"}]}`

Results: Filters contains invalid key: none

I would expect this to work because it is documented here: https://swiftype.com/documentation/app-search/api/search/filters#combining-filters

When using the all filter, I do get the a correct result.
"filters": {"all": [{"tag": "swiftype_dashboard"}, {"tag": "swiftype_dashboard_query_tester"}]}

Is there another way to exclude certain tags? I do not want to display searches done in the Test UI.

Kind Regards,

Sam
